Can't comple catkin_ws

[EricDiazR]

Hello.

I can't compile catkin_ws. It shows the following message:

-- Eigen found (include: /usr/include/eigen3)
-- +++ processing catkin package: 'rotors_gazebo'
-- ==> add_subdirectory(rotors_simulator/rotors_gazebo)

I followed the instructions from the readme file. But i didn't clone the bebop_autonomy git cause i already had it (the anqixu fork that solves the compilation on ROS melodic)

Im running ubuntu 18.04 with ROS melodic

Thank you in advance.

Thanks for opening your first issue here! Make sure that no other issues on the same topic have already been opened!

Hi! We need to understand if the bebop_autonomy dependencies are causing the issue. Please, try excluding the package from the build. Simply, removing it from the folder containing all the ROS packages. Hence, compile and a simple example file. You should be able to install and use BebopS even without bebop_autonomy.

While using rosdep i get the following error message:
~/catkin_ws$ rosdep install --from-paths src -i

ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
bebop_simulator: Cannot locate rosdep definition for [bebop_driver]

And when trying to compile the catkin_ws i get the following (using catkin build)
Errors << rotors_gazebo_plugins:make /home/eric/catkin_ws/logs/rotors_gazebo_plugins/build.make.000.log

After clone the official bebop_autonomy package, rosdep gives no error.

But i still get the previous error

And if i use catkin_make instead of catkin build, i get this error (the same as the first comment of this issue):

Ok, got it. Remove bebop_autonomy from the src folder. Then, run again the sudo rosdep command, and finally catkin build. It should work.

Hello, I had the exact same error as @EricDiazR .
In my case, simply the version of OpenCV was different.
I suppose the rotors_simulator code was written with OpenCV version lower than 3.0. (This might be useful: 'CV_LOAD_IMAGE_GRAYSCALE' is not defined{PY})
In my environment, I use ROS melodic + Ubuntu 18.04 + Gazebo 9 with OpenCV v3.2.

I had to;

• add #include <opencv2/imgcodecs.hpp>
• change from https://github.com/gsilano/rotors_simulator/blob/5c36c7f2affe42dbeabbf27601aeb0fc6fbc9093/rotors_gazebo_plugins/src/gazebo_odometry_plugin.cpp#L94 to covariance_image_ = cv::imread(image_name, cv::ImreadModes::IMREAD_GRAYSCALE);

Modifying these solved the issue and I can compile packages now.

@gsilano , original package with the latest version is doing the same thing. Please consider git pull from the original repository.

Hi @SarahMars! Thanks for the info. I just created a new branch in my RotorS fork. I will update the README.md file with the instructions.
